Aquascaping Lab – ROTALA Aquatic Plant technical description and management (all varieties)

Welcome on Aquascaping Lab channel in this video tutorial we are talking about Rotala aquatic plant and all varieties Rotala derives from Lythraceae family and originates in the areas of South / East Asia they are stem plants with a very rapid growth that require a constant supply of nutrients They are among the most used aquascaper plants for their beauty and colors ranging from green to red depending on the species generally, given their height that can reach 30/50 cm they are used as plants for the background Let’ see now the most famous kinds of Rotala plants Rotala Rotundifolia: It is native to South East Asia (China, Myanmar, Vietnam) and Japan has a very fast growth, and with its reddish-orange color which assumes with presence of light, but green if there is little light it gives a nice contrast with the greens of the other plants The Latin name means “from the round leaves”, and infact the plant grown out of the water in the hydroponic crops of large aquarium plants, has beautiful round leaves but when it is placed in the tank, completely submerged the new leaves that develop in water are not absolutely round, but thin and elongated even 2-3 cm or more It grows very quickly and requires a lot of light to maintain its natural reddish color (in addition to a fair fertilization with iron) It is found quite frequently in commerce It tends to form aerial roots that cling and everything and easily intermingle as its stems behave almost like they were stolons, bending towards the ground to propagate It can reach incredible lengths If planted too thick, the lower part suffers the lack of light and loses the leaves Rotala Indica: Known as Rotala ‘Bonsai’ is a very small plant suitable also for Nano Aquariums It is a kind of medium difficulty that needs good light fertile background, CO2 and careful fertilization It is cultivated in groups by planting the stems very close together With bright light the tips become a very intense orange and the plants remain low and compact With less intense light the stems tend to stretch a little longer, remaining almost green. Rotala Macrandra: Type of marsh Rotala with prostrate bearing and green color in emergence has an erect bearing and color from pinkish brown to red / orange submerged Opposite leaves, two for whorl, which in submergence are presented with oval shape slightly sharp, with wavy margin, pinnate rib and without petiole In submergence the single stems can reach 40/50 cm in height Rotala Wallichii: The Rotala Wallichii consists of a single stem which in submerged form generally does not branch but can reach up to 40-45 cm in height It is a whorled plant, that is, with the leaves arranged all around the node, like the spokes of a bicycle The name “Rotala”, assigned by Linnaeus to this genus of plants derives precisely from this characteristic, common to several species This arrangement concerns both the emerged and the submerged form but the general appearance is very different Under the leaves the leaves are thin, very thick and numerous and there can be up to 15 for each whorl In emergence, however, they widen up to 4 – 5 mm, assuming an elliptical shape but it is rare that there are more than 5-6 on the same node Rotala reproduces by cuttings so it is possible to cut with a pair of sharp scissors the upper portion of the stem which must be at least 10 cm long; the lower portion (usually more ruined) can be left in the ground or uprooted To reproduce it the new upper portions are buried in the substratum practicing a small hole with the finger; you place the cutting at about 3-4 cm deep in the hole and cover with the surrounding sand, the tufts that must be maximum of 2 or 3 stems should be planted at a distance of one from the other of 3/4 cm to allow the light filtration even in the lower parts Remember that in the presence of high concentrations of iron and near intense light sources, it may take on reddish colors It can be grown in closed and open aquariums the substrate must be fertilized, since the root system is very developed it must be planted in groups, better if numerous the various plants can be buried at a distance of at least 3-4 cm between them and the other neighboring plants Requires the use of complete fertilizers both liquid and solid with chelated iron and potassium we suggest the administration of CO2 and strong illumination not less than 0.5 w / l is recommended if you are interested to buy the Rotala plant, you must to know that the price is around 5 € for 1 vase thank you for watching tihs video tutorial if you want to know more on plants and aquascaping read the full article and visit our official website clicking here or in the info click on like and leave a comment for any question subscribe on our Youtube channel for all news thank you
